Bamboo-steel composite structure contains all kinds of composite structural members, widen the applied range of bamboo and implement the diversification of component materials and forms in building structures.
If combine the two materials reasonably, can give full play to its function, and to a certain extent to save energy, making a building structure light and environmentally friendly.
Therefore, thermal insulating and soundproof materials such as EPS particle and pipelines such as electrical wire can be placed in the wall.
The experimental results indicate that the composite beams can form an excellent composite crosssection and have a good whole work performance, which is an effective way to utilize the materials.

A Preconditioned Gauss-Seidel Iterative Method for Linear Complementarity Problem in Intelligent Materials System Duan Banxiang1,a,Zeng Wenying 1,b and Zhu Xiaoping1,c 1 Computer Engineering Technical College, GuangDong Provincial Institute for Technical Personnel, Zhuhai, Guangdong 519090, China aduanbanx@hotmail.com, bzengwenying@126.com, cganzxp@263.net Keywords: Linear complementarity problem; H-matrix; PGSI method; preconditioned matrix; convergence.
Lastly we report some computational results with the proposed method. 1.Introduction For given matrix and vector , the linear complementarity problem consists of finding a vector which satisfies the conditions (1) Because the has a variety of applications such as the Nash equilibrium point of a bimatrix game, contact problems, the free boundary problem for journal bearings, etc.
